LM2623AMMX/NOPB datasheet by Texas Instruments

LM2623AMMX/NOPB Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the LM2623?
  The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and output current requirements.
• How do I ensure stability in the LM2623 voltage regulator?
  To ensure stability, use a minimum output capacitor of 10uF, and ensure that the output capacitor's ESR (Equivalent Series Resistance) is less than 1 ohm.
• What is the maximum input voltage that the LM2623 can handle?
  The maximum input voltage that the LM2623 can handle is 15V, but it's recommended to keep the input voltage below 12V for optimal performance.
• Can I use the LM2623 in a high-temperature environment?
  The LM2623 is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Ensure proper thermal design and heat sinking to prevent overheating.
• How do I calculate the output voltage of the LM2623?
  The output voltage of the LM2623 is set by the resistor divider network (R1 and R2) connected to the FB pin. Use the formula: Vout = 1.25V x (1 + R2/R1) to calculate the output voltage.
